ILOCK MECHANISM FOR REVERSIBLE WINDOWS.

srnoi rron'rioiv forming part of Letters Patent No. 655,382, datedAugust 7, 1900. Apnlication filed March 26, 1900. Serial No. 10,195. (Nomagi.)

To all whom it may concern; V

Be it known that I, WILLIAM H. TALBOT, a citizen of the United States,residing at the city and county of San Francisco, State'of California,have invented certain new and useful Improvements in Lock Mechanism forReversible W'indows; and I do'hereby declare the following to be a full,clear, and exact description of the same.

The present invention relates more especially to certain new and usefulimprovements in the means for lifting or actuating the lock rod or barforming connection be tween the window-sash and the slide shoe or blockof reversible windows; and the objects of the invention are to simplifythe actuating means for the lock-rod, reduce the expense ofmanufacture,and at the same time enhance the appearance of the window.

In order to understand the invention, reference should be had to theaccompanying sheet of drawings, wherein- Figure 1 is a general viewdisclosing the upper sash of the window partly broken away. Fig. 2 is avertical sectional view taken on line a; a, Fig. 1; and Fig. 3 is adetail view of the lock-rod and its actuating mechanism.

In the drawings the letter A is used to indicate one of thewindow-sashes, which is slidable with relation to the casing A of thewindow and of such a width from side to side as will permit of turningbetween the partingstrips of the casing. The sashes are guided by thegrooves or channels A within which are fitted the slide shoes or blocksA To these slide shoes or blocks the sash is pivoted at about the centerby suitable centerpins. The slide-shoes are formed with channels 13,extending vertically, and corresponding channels B are made in thesashes. IVithin these channels in the sashes are fitted the lock-platesB preferably made of metal and of a thickness which will permit them tobe moved into the channels B in the slide-shoes, so that when in thisposition the sashes and slide blocks or shoes will be locked togetherand will then be slidable up and down in the channels in the casing inthe manner of an ordinary window. When thelock-plates are moved into thechannels B in the sash, so as to be disengaged from the sliding blocksor shoes, the sash will be free to turn about its pivot-pins, as beforedescribed. These lock rods or plates vB are provided with inclined slotsa a near their upper and lower ends, and these slots fit over pins awhich are fixed in the sashes at each side, near the upper and loweredges, and upon these pins the lock bars or plates ride and raise andlower as moved inward and outward, owing to the inclination of theslots. It will be understood that as the lock plat-es or bars movedownward and outward they enter the channels B inthe slideshoes, andthus lock the same to the sashes.

In the channels B of each sash,nearits lower edge, is fitted a stirrupor' guide C, within which the lower portion of the lock bars or plateswork. That portion of the lock plates or bars working in said stirrup orguide is provided with a T-shaped opening C, within which is fitted thehead C of the releasingrods D. ing in the rear edge of the guides orstirrups C, and the ends thereof are screw-threaded, and onto the samescrews the shank D, carrying at its outer end a button or knob D Theshank D of the releasing-rods. works through transverse openings 12 inthe sash, the knob or button D projecting slightly beyond the inner edgeof the sash. The shank D is held in place and prevented from beingunscrewed from its rod D by means of the keeperplate 17, which plategives a finish to the sash at this point.

When it is desired to raise the lock plates or bars B in order todisengage the sash from the slide shoes or blocks, it is only requiredthat the releasing-rods D be drawn outward by drawing the knob or buttonD at each side of the sash outward, Fig. 2. IVhen thus moved, theenlarged head C pulls against the inner wall of the opening C and forcesthe lock bars or plates inward, causing the same to ride upon the pins aand move upward within the channels B of the sash. To relock the parts,the knobs or buttons D are forced inward, which movement forces the headC against the outer wall of the opening 0 and causes the lock plates orbars to move downward and outward into the channels B of the lock shoesor plates. When the releasing-rod is thus forced inward to cause thelocking of the sash and slide-shoes, the knobs or buttons are all thatis noticed to distinguish the sash from These rods extend through anopenan ordinary slide one. The said knobs or buttons serving merely forthe purpose of a handle by which to actuate the releasing-rods, the samemay be constructed in any suitable manner or ornamented as desired.

Having thus described the invention, what I claim as new, and desire tosecure protection in by Letters Patent, is

1. In a window of the described character, the combination with thesashes, of the slide blocks or shoes, vertical grooves or channels inthe slide-shoes and the edges of the sashes in line with each othervertically, the vertically-slidable lock-plates fitted in said groovesor channels, of transversely-movable releasing-rods working through thesashes, and of a free or movable connection between the inner end ofsaid releasing-rods and the lockplates whereby the inward and outwardmovement of the releasing-rods serves to vertically move the lock-platesout of and into engagement with the slidesh0es.

2. In a window of the described character, the combination with thesashes, of the slideshoes, vertical grooves or channels in theslideshoes and edges of the sashes in line with each other, slidablelock plates fitted in said grooves or channels, said lock-plates havinginclined slots therein at their upper and lower end portions, pinsextending into the channels or grooves of the sashes and upon whichthe'lock-plates ride as moved inward and outward, a" T-shaped slot ineach lock-plate, a

transversely-movable releasing-rod working through the sashes, said rodhaving an en larged head fitted within the opening of the lock-plates.

3. In a window of the described character, the combination with thelock-plates, of the transversely-movable releasing-rods for actuatingthe same, said rods comprising, an enlarged head fitted within anopening in the lock-plates, a screw-threaded stem extending therefrom,and a knob or button having a shank screwed onto the screw-threadedstem, said releasing rod working through transverse openings in thesides of the sashes.

4. In a window of the described character, the combination with thelock-plates fitted to move in vertical channels or grooves in thesashes, a stirrup or guide secured within said channels or grooves, areleasing-rod working through said stirrup or guide, the same com-.prising, an enlarged head fitted within an opening in the lock-plates,a stem extending from said head and a knob or button secured to theouter end of the stem,-said releasingrods working through transverseopenings in the sides of the window-sashes.

In witness whereof I have hereunto set my hand.

WILLIAM H. TALBOT.
